The process permits to strengthen a lever made of ceramic material. Ceramics is strong, but brittle, thus, in the course of lever operation it may undergo external mechanical forces, such as sudden impact, that generally cause cracks and spalling. After such damage ceramic pieces may separate from the ceramic support. The utility proposes to strengthen a ceramic lever with a special glue coating made of one of series of thermoplastic glue melts and applied to the internal surface of ceramic lever cavity. The solution has as its object to improve a ceramic lever strengthening process comprising application of glue coating made of a series of thermoplastic glue melts to the internal surface of a ceramic lever cavity according to which the glue coating undergoes thermal treatment at between about 80° C. and 180° C. before application to the internal surface of ceramic lever cavity.
